Este tipo de noticias me constipan aun mas........ haaaaaaaaaaaaaaaaaa pero si dan ganas de odiarla, pero no puedo, esa es su gracia, le cae bien a hombres y a mujeres...
Resulta que la señorita, que cumplio los 26 años este 9 de junio Natalie Portman (cuyo nombre verdadero es Natalie Hershlag...) Estudio en Harvard, eso no es noticia para ningun fans, tampoco es noticia el hecho de mientras curso sus 4 años en Harvard, paso sus veranos trabajando en peliculas... y que posee un titulo de Psicologia (tambien he leido que tomo cursos de Literatura Clasica...y politica internacional...) y que por estos dias esta bastante involucrada con la Campaña de Finca y el Village Banking, que busca financiar a las mujeres pobres del tercer mundo, en el inicio de sus negocios...
Ahora sale a la luz publica que tambien fue co-autora de un apunte cientifico sobre el desarrollo de la neurociencia infantil...
Natalie fue uno de los asistentes de investigacion del Prof Stephen Kosslyn's en el laboratorio de neurosicología, donde se vio involucrada en una investigacion ligada al desarrollo del Lobulo_frontal y el conocimiento visual de los infantes...
The study investigated object permanence - the ability to understand that objects do not disappear from the world when they are out of sight, something that typically develops in the first year of life.
Researchers have argued that the frontal lobes are particularly important for this skill, but the trouble is, you can't put babies in conventional brain scanners to easily test the idea. They just wriggle about too much.
Portman's study, led by neuroscientist Dr Abigail Baird, used a relatively new method for measuring brain function called near-infrared spectroscopy.
This technology relies on the fact that near-infrared light can penetrate the skull, and that blood carrying oxygen, and blood that has given up its oxygen, absorbs the light differently.
The idea is that the device beams light into the frontal lobes, and you can work out how hard this area is working from how much oxygen-rich blood there is.
The advantage is that this technology is safe for children, and can be worn as a sort of high-tech hat, meaning there's less of a problem if the child being tested moves about.
During the study, infants were shown a toy, which was then hidden under a cloth. Children who have object permanence - who know that it hasn't disappeared - look for it under the cloth.
Children without this skill just ignore the cloth and look for something else to do, because the memory of the toy is gone.
The study tested 20 infants, every four weeks, from the ages of 5-12 months. To see what changed in the brain as the ability emerged, the researchers compared infrared light absorption from a time when the kids first looked for the toy, to an earlier time, when they just forgot that it existed when it was out of sight.
The team discovered that the frontal lobes suddenly kicked in when children develop the knowledge that hidden objects still exist, providing an understanding of which brain areas are involved in this important mental function.
The study also demonstrated that near-infrared spectroscopy could be used successfully to study the brain development of very young children.

El documento fue publicado por el journal Neuroimage, bajo en nombre real de Natalie, con el titulo de 'Frontal lobe activation during object permanence: data from near-infrared spectroscopy'.
Esta investigacion, ha sido citado por al menos 20 estudios mas, construidos en base al mismo, si te interesa leer el estudio, acá está el documento en pdf por supuesto que en inglés...
